Definitions

  • the invention is based on a suspended filter ceiling for separating and precipitating suspended matter from rising exhaust air, with identical, horizontally and mutually parallel, curved ceiling elements and identical, also mutually parallel, but at a distance below the side edge parts of two adjacent ceiling elements each which ceiling elements and gutters are supported by cross beams.
  • Such a filter ceiling is described in AT-A-352 959. With such a false ceiling, an attempt is made to achieve as complete a separation of the condensate as possible. In order to achieve the most complete possible condensation, the side edge parts of the ceiling elements have an outward curvature in their end region. The exhaust air flowing along ceiling elements designed in this way forms a vortex or circulation flow. It is believed that such a flow causes increased condensation.
  • a disadvantage of this solution is that the number of rooms in which eddy or circulation flows of the exhaust air are too small to achieve a complete condensation of the suspended matter contained in the exhaust air.
  • CH-A-625 035 describes a device for ventilating rooms with a humid and / or rich atmosphere.
  • the suspended ceiling here consists of backdrops that are arched in cross section. The be each other neighboring scenes are alternately arranged with their longitudinal opening up and down, where they interlock.
  • the baffles intermesh at a distance such that a chamber which widens the flow cross section is formed between the narrowing of the baffle edges. On the way of the air flow, the chambers serve as calming rooms, in which contaminants in the exhaust air easily turn out.
  • the invention specified in claim 1 was based on the object of providing a suspended filter ceiling for separating and precipitating suspended matter from rising exhaust air, with which a much higher degree of separation and precipitation of suspended matter is achieved than in the known filter ceiling. Furthermore, the components of the filter false ceiling should be easy and inexpensive to manufacture.
  • a calming space is advantageously formed in the direction of the exhaust air flow behind each compression space, the volume of the successive calming spaces increasing.
  • both the air deflectors and the gutters are removably attached to cross members.
  • a method for producing the filter false ceiling is characterized in that the ceiling elements, the gutters and the air outlet baffles are each deep-drawn in one work step, a hole being punched out in the region of the side edge portions of the ceiling elements to be formed and the collecting channels being closed on their transverse sides.
  • the filter ceilings shown in the figures which can be suspended from the ceiling of a room, are used for separating and precipitating suspended matter from rising exhaust air. B used in industrial kitchens, slaughterhouses or in large-area paint spraying systems.
  • the filter ceiling can be in the form of a cassette or not used as a cassette, but only as a filter element.
  • the filter false ceiling shown there has several identical, horizontal and parallel to each other fende, arched ceiling elements 1, which consist of thin sheet metal profiles.
  • the ceiling elements are usually welded to the cross members 3.
  • the side edge parts 1a of each ceiling element 1 are V-shaped in cross section.
  • the ceiling element 1 is designed so that the incoming exhaust air is guided along the curved contour of the ceiling element 1 to its side end parts 1a.
  • gutters 2 Below side edge portions 1a of two adjacent ceiling elements 1 run parallel to each other, identical gutters 2.
  • the gutters 2 are also carried by cross members 3, wherein they are removably attached to the cross members 3.
  • the gutters 2 can be easily removed from the filter ceiling.
  • the gutters 2 with a U-shaped cross-section surround the side edge parts 1a of the ceiling elements 1 at a distance.
  • the air baffles 4, 4a according to FIGS. 1, 2 and 6 have essentially the shape of an inverted U l s in cross section.
  • the air baffles 10 shown in FIG. 4 consist of identical baffle plates. Each link plate has on its side edge parts each a link 16 with a circular arc in cross section.
  • the two sets of two adjacent set plates each have openings 17 which are opposite to one another but are laterally displaced.
  • the two baffles 16 arranged one above the other lie above the side edge parts 1a of two adjacent ceiling elements 1.
  • the embodiment of the air baffles 4a according to FIG. 6 differs only from that according to FIG. 2 there that the legs of the inverted U are angled so that the angled end parts form a sharp angle with the other parts of the legs.
  • the air baffles 4, 4a, 10 are also removably attached to the cross members 3 so that they can be used for cleaning, for. B. in dishwashers, can be easily removed from the filter ceiling.
  • Both the gutters 2 and the air baffles 4, 4a, 10, which each have bent overlaps 26, are removed from brackets 18 in the cross members 3.
  • slots 27 are provided in the ceiling elements 1 in their edge parts fastened to the cross members 3 (see FIG. 5).
  • the brackets 18 are so tight that it is not possible to move them while the filter ceiling is in operation. No handling errors can be made when reinstalling the gutters or air baffles after cleaning.
  • the ceiling elements 1, the gutters 2 and the air deflection plates 4, 4a, 10 can consist of steel sheet, aluminum sheet, chrome steel sheet or chrome nickel steel sheet. It is advantageous if these materials are partially or completely coated with "Teflon" or with a similar plastic or with enamel. Such a coating ensures that cleaning is carried out hygienically clean with extremely little fat-soluble detergent. Plastic is another possible material. The components coated with Teflon can also only be rinsed off with a shower, because such a coating has proven itself in practice to be particularly oil and fat repellent.
  • the ceiling elements 1, the gutters 2 and the air deflectors 4, 4a, 10 are each in one ar deep-drawn as a single piece. After the ceiling elements 1 have been deep-drawn as a single piece, a hole 18 is punched out in the region of the side end parts 1 a of the ceiling elements 1 to be formed.
  • the gutters 2 are closed on their two transverse sides. This measure prevents the filtered condensate from flowing out of the gutters 2 or running out when the same is removed for cleaning.
  • the mutually arranged collecting channels 2, side edge parts 1a of the ceiling elements 1 and the air deflectors 4, 4a, 10 create a labyrinth-like system in the filter ceiling, through which the exhaust air is guided and in which various separation and precipitation processes take place.
  • FIGS. 2, 4 and 6 several compression and calming zones are created by the shape of the side edge parts 1a, the ceiling elements 1 and the air deflection plates 4, 4a, 10 on the way of the exhaust air flow.
  • a first compression zone 5 is created between the bent part of the side edge section 1a of each ceiling element 1 and the collecting channel 2, a first calming zone 11 in the widened space between the bent part of the side edge section 1a and the collecting channel 2, a second compression zone 6 between the tip of the side edge part 1a of each ceiling element 1 and the gutter 2, a second calming zone 12 in the widening part between the inclined legs of the side edge parts 1a of two adjacent ceiling elements 1, a third compression zone 7 between the tapering legs of the side edge parts 1a of two adjacent ceiling elements 1, a third calming zone 13 in the space closed off by the air deflector 4, a fourth compression zone 8 between the end region of the leg of the inverted U of the air deflector 4 and the curved part of the side edge part 1a of each ceiling element 1 and a fourth calming zone 14, which in the embodiments according to FIGS.
  • FIG. 2 and 6 represents the ceiling cavity.
  • it is additionally the compression zones 9 at the exit from the calming zone 14 formed by the two scenes 16 and the calming zone 15 which represent the ceiling cavity.
  • the embodiments according to FIGS. 2 and 6 are therefore four compression and four calming zones, the embodiment according to FIG. 4 having five compression and calming zones.
  • a compression zone and a calming zone are alternately formed in the direction of the exhaust air flow, the volumes of the successive calming zones increasing.
  • the residual condensate is separated out by the cooling of the exhaust air in the calming zones which increase their volume one after the other, in particular in the calming zones 14, 15 forming the ceiling cavity.
  • FIG. 7 shows a suspension profile 19, which is inserted into a longitudinal groove 20 of a support profile.
  • the suspension profile 19 and the support profile 21 two adjacent cross members 3 are held which support the filter ceilings.
  • a rivet is designated which connects the suspension profile 19 with a suspension band 23.
  • the suspension band 23 is fastened by means of a screw 24 which is screwed into a dowel 25 inserted in the ceiling.
  • the shape of the ceiling elements 1 and that of the air deflection plates 4, 4a, 10 ensures that behind each compression zone in the calming zone ne There is a vortex or circulation flow of the exhaust air.
  • the suspended matter in the exhaust air such as water, fat and oil particles, is separated out by the vortex or circulation flow and precipitated in the collecting channel 2 or in the scenes 16.
  • the shape of the ceiling elements 1 and the air deflectors 4, 4a, 10 prevents the condensate flowing in with the exhaust air from directly reaching the ceiling cavity and from there into the ventilation duct or heat recovery part and fan in the event of an overfilled gutter 2 and these parts or devices are dirty. Also by this shape z. B. fire protection achieved in commercial kitchens because the rising flames are smothered in the labyrinth system and thus do not get into the ceiling cavity or into the duct system or other rooms.
